Early in the day, long before dinner, wash your potatoes and allow them to completely dry before preparing for dinner. Preheat the oven to 350.

One hour before dinner, pour the Tbs of vegetable oil on a paper towel and rub the oil over the entire outside of the baked potato. Over the sink, sprinkle the oiled potato with kosher salt so that the oil adheres to the potato. Most of the salt will fall off of the potato - you might want to put a plate under the potato and catch the salt and use it on the next potato. That is up to you. Using a sharp knife and poke at least 4 holes into each potato.

Place the potatoes bare skinned directly onto the rack of the oven. Bake for 45 minutes. Remove from the oven and allow to rest for 10 minutes. You can bake as many potatoes this way as will fit in your oven.
